Application ledrelruly 6,

To aZZw/lomz'tmayaonc'em: V

Be it known that I, WILLIAM Tarn, a citizen of the United States,residing at High Point, in the county of Guilford and State of NorthCarolina, have invented new and useful Improvements in Attachments 'forShaping Machines, of which the following is a specication.

This invention relates to improvements in shaping or cutting machines,andl has as its object the provision of an attachment for such machinesadapted torassist in guiding and gauging the stock'duringits-presentation to the cutting devices. Y

This invention is an improvement upon the device of my Patent No.1,435,758, granted Nov. 14;, 1922, in which there is disclosedv a rigidguide sleeveA positioned below the cutter head and against which thestock, or a supporting pattern or carrier block may -be pressed inpresenting the stock to the cutters. Asset forthin the patent,

the use of such a guide prevents vibration of the material bythe cutterspindle as occursV when the .stock engages a guide-1 mounted' uponl thespindle, and insures a uniformly smooth and unscored finished surface,which is not always obtainable when the Vmaterial must engageaguidewhich rotates withthe spindle. I E Y An object ofthe presentinvention is to provide a rigid stockV guide or gauge p-ositioned abovethe cutter head which may supplement or maybe usedin lieu of the gaugedisclosed in my former patent.

A further object of the 'invention is to provide a mounting or supportfor the additional ide and gauge whereby the same is maintained in Xedrelation with the cutter head and is vertically movable Vtherewith whenthe cutter spindle is adjustedv relative tothe worksupport. l o

A' further ob'ect of the invention is to provide means for adjustingVthe guide relative to the cutter head `vso that thelsame may be' adaptedfor use in. conjunctionywith variousv Y sizes and types of cutters ortools of wood shaping machines.

Furthenfthe invention seeks a wood shaping'machine, and which `carriesboth the `lower guide sleeve and the upper guide sleeve; with both ofthe sleeves inde' pendentlyadjustable relative to the cutter head andmounted sothat Yboth may be moved 'with the cutter spindle, which must'l maintain the arm in-iXed position.

obvious as the description proceeds in connection with a preferredembodiment of th-e invention disclosed in the accompanying drawings,wherein Fig. 1 isad fragmentary elevational view of a wood shapingmachine showing the at-V tachment applied thereto, and

view.

Referring'to the drawings Vfor a more de.-

tailed description, 10 indicates abed plate or work-.table providedrwithan opening 11,. .K A through which projects a spindle 12 lhavingbearings 13, 14 in a slide15 which is vertically adjustable inlguideways 16 beneath the bed plate. vThe slide carries aV cross arm Fig. 2 is,l a fragmentary vertical sectionalY 17 having a threaded"opening receivin a screwl shaft-18V mounted beneathf the ta le L Vandrotatable by means of a hand wheel19 operativelylconnected in anysuitable manner for rotation of the shaft. A

The upper end of the spindle carries la 'Y pair of spaced collars 20, 21betweenrwhich are mounted cutter :bars V22, 23; and a nut-24;Y

above the collars serves to clamp the cutters in position. Thespindlefmay be driven in any suitable manner, Aas by means of a pulley25 Xedly mounted thereon so las to be engaged by-a belt drivenfrom any.Asuitable source or power (notshown).

The construction above described old` and well knownV in the art and, asshown in theV drawings, is merely conventional in order to make clearthe application of .the invention, which is'not limited either to theVparticulartype of. bed plate or cutterl head assembly 'shown anddescribed. It will be noted, however, that, broadly, the machinecomprises a vertically[adjustable spindle f aY cutter head assembly.

mounted in a suitable support and carrying' Vlositioned above thecutters and surround-V carried by an arm 27 which is mounted upon astandard 28. The arm is adjustable' along the standard, which: extendsthroughan opening in the end of the arm; 'a set screw l30 is adapted-toengage the standard and The fing the spindle is a suitable stock guide'and gauge, in the present instance a sleeve-26 toV provide an.attachment which maybe readily 'applied to Y tion 31 which fits in anopening 32 of alsuitf Y able supporting armv 29 lbeneath-:the bed plateandiis held against rotation .by means ot' a nut 33 threaded upon theshank. Obviously, when the nut 33 is loosened and the standard 28rotated upon its support and Within the lopening in thearin 27, thelatter, together with the guide sleeve, Will be adjusted to center thesleeve Withl respect to the shaft, this being due to the fact that theshank ot' the standard. is eccentric with respect to the longitudinalaxis of the remainder of the standard.y Y

The support 29 is,- preterably, mounted. upon the spindle slide l5 sothat the guide sleeve Will be maintained. in vfixed relation v'ith ythecutter head When the spindle and cutter head are vertically adjusted;this will eliminate the necessity for independently sett-ing the gfuidesleeve With respect to the cutter head Whenever the spindle is adjusted.The arm 29'is carried by a bracket 34 which is secured, by means ot'screws to the arm and the slide l5. lt Will thus be noted thatWhenever'the slide is adjusted the r arm, standard 28, together with itssleeve supporting. armm, will be moved with the spindle and the cutterhead. t

It' Will be noted that the supporting arm 29 has an extension collar 36internally threaded to receive a lower guide sleeve 88 such as is shownin my patent, referred to above. rlhe sleeve 38, dueto its threadedengagement with the collar 35, may be vertically adjusted relative tothe cutter head by rotating the same, and any suitable holding'ineaiisv` (not shown) may be provided to maintain the-sleeve in linedposition, asset forth in .my patent. Additional holding means, such as,the screws 35 passing through the collar into thetop of the slide 15,may be providedl for the purpose ot maintaining the collar and standardsupport` securely4v in position.

Although it is not necessary, for the purpose ot' carrying out myinvention, to provide the collar Soupon the support 29 for the standard,Ysince the latter may be independent of the collar and separatelyattachable to the slide, it will be understood that'f'the constructiondescribed affords a complete attachment which may be readily positionedupon practically any form of shaping machine. rIhe lower guide sleeve 38may be adjusted by .rotating the saine -in theA collar 86, and the uppersleeve 26 may be independently adjusted by moving its arm 27 along thestandard 28,; the set screvi7 S50-being' provided for lthe purpose ofmaintaining it in any selectedA position. ldoreover,r the upper sleevemay be centered with respect to the spindle and cutter .head by rotatingthe standard -28, which is accomplished by loosening the clamping nut33. Theadjustment's referred to permit the adaptation of the attachmentto rnodii'iedr forms of cutters-and permit theuse ot the attachment Withstock Whichfmay vary considerably in thickness.v

lt will also be observed that both of the guide. sleeves are removablefrom the support; for removing the upper sleeve it isl simply necessaryto loosen the set screw `30 and slide the arm-27- iirom the standard andthe lower sleeve may be removed by unscrovv" ing the same from thesupporting collar 36;

When' the guide `sleeve is to be usedwith'. larger and modified .formsot cuttersA a collar 26 may be threaded upon the upper end thereot', andthe same may be removed when interferes Awith operation. upon stoel; orWith the use of lthe guide inY connection With cutters such as are shownin the drawings,... .I 1 j Both ot' the 'guide sleeves, which may beusedi'sepanately or to',' jether,v constitute fixed and rigid guidesagainst ivhich the stock or pattern block may be `pressed when the may`be accurately c utandfwi'll `always be Y oundto be smooth anduns'cored: through# out its extent. YAnd, Whenever the vcutters areadjusted vertically With respect to thev/orltV support or bed plate,which is accomplished by rotation of anysuitaole adjusting means, in thepresent instance the handl Wheel 19, both guiding sleeves ivill beadjusted t'l'ieret'vith, thusinaintaining the desired relation 'betweenthel sleeves and cut-l ters and eliminating the necessity for Aresettingthe sleeves vvlienevertlie spindle and cutters are adjustech j It-should'be iinderstod ythat numerous modilications may bemade in thestructure `which has been illustartedand described in detail Withoutdeparting Vtrom the scope or the invention, vvlhich is more definitelydened in the following claims.
